Secure video player -watermark on video

Im looking for someone who could make it for me.
How it would be work

  1. user login to page and put his personal data (name, surname, mail, etc)
  2. He has access to video but all videos have watermark with his personal data.
    If he download it it still be with his name, surname, mail etc, so propably he wouldnt share it.

If you have anny suggestion to protect video in another way, please contact me.
